Topsøe process to be used at two Chinese SNG plants
Topsøe has been awarded contracts for two large plants that will produce of substitute natural gas (SNG) from coke oven gas. The contractor is China National Gas Corporation Limited (CNGC), which is organized under the PetroChina Group.
The plants will be located in Wuhai, Inner Mongolia, China, and will be part of a larger plant that will convert “waste” coke oven gas into clean and valuable liquified natural gas (LNG).
The inclusion of Topsøe’s process will increase the production of LNG by 90%, which will add considerable value to the project and increase utilization of the “waste” gas.
“Wuhai project is a true green project to convert waste gaseous emissions into clean LNG-fuel,” said Gao Qin, vice general manager of China Natural Gas Wuhai. “The creative approach is profound: The success of the project will set up a model to the sustainable development of China energy industry.”
In Topsøe’s process, carbon dioxides are converted into SNG. The SNG is liquefied to become LNG. The plants will have a capacity of 1 billion normal cubic meters of LNG per year. The plants are planned to be in operation by the end of 2012.
The LNG will be transported by truck to distant end users and used in, for instance, fuel stations.
